FLUSHlNG-TANK.

SPECIFICATION forming part of Letters Patent No. 774,766, dated November15, 1904. Application filed February 14, 1903. Se a NO- 143,316. (Nomodel.)

T0 60% whom, it warty concern Be it known that I, HENRY J. LUFF,acitizen of the United States, residing at Cleveland, in the county ofOuyahoga and State of Ohio, have invented new and useful Improvements inFlushing-Tanks; and I do declare that the following is a full, clear,and exact description of the invention, which will enable others skilledin the art to which'it appertains to make and use the same.

My invention relates to improvements in flushing-tanks forwater-closets; and the object of the invention is to provide means whichwill both disclose leakage therein and provide for the escape of leakingwater therefrom to the end that the tank may not be injured by suchleakage and the parts therein protected from rust and corrosion and alsowhereby certain soldered pipe connections may be made and not hithertopossible, all substantially as shown and described, and particularlypointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective elevation of awatercloset equipment, including bowl -and tank connections. Fig. 2 is aperspective view of the tank alone, showing the cover lifted in inclinedposition; and Fig. 3 is a perspective view of the tank-lining and itssupporting-base. Fig. i is a plan view of the tank complete on across-line corresponding, say, to w m, Fig. 5. Fig. 5 is a verticalsectional elevation on a line corresponding to y y, Fig. 4.

The tank or reservoir thus shown is constructed with an outer casing A,of wood preferably, and the tank or reservoir within the same having apreferably brass or other like hard plate bottom B aboutthree-sixteenths of an inch in thickness and having lead, copper, orother like soft metal side C soldered thereon or otherwise permanentlyaffixed thereto. The said inner or water tank is separated from the wallof easing A by ribs or cleats a vertically at intervals, and whichafford ventilation in the intervening space, and the bottom B has aflange b all around let into recesses in the adjacent sides of thecasing all around relatively, as seen in Fig. 5, so as to intercept anymoisture which may come from leakage in tank C or otherwise into thatspace, and I form a groove 0 all around on the said flange 6, and whichhas one or more outlets 2 in its bottom corresponding with openings 3 inthe bottom of easing A. These openings serve to give warning if leakageoccurs before it will become serious, and a pail or other vessel can beused to intercept the drippings. The inner wall of the casings may betarred or shellackedto further protect it, and its bottom D is aremovable part fastened in place by screws and among other things servesto bear up against the outer grooved flange 6 of tank-bottom B and pressit to its seat in the outer casing and hold the water-tank in position.

Another material advantage of my construction is the possibility ofsoldering the usual service-pipes connected with the bottom of the tankinstead of fixing them thereto by a joint or connection requiring nutsand gaskets, as heretofore, and which were liable to become leaky. ThisI can do because I have a brass bottom B, with which this pipe E isconnected by soldering, as shown, and whereby a rigid and durableconnection is made.

The cover H and easing A have coincident vent-channels it to promoteventilation within the tank structure.

The advantage of two metals for the tank O lies in having the body ofthe tankof lead, as usual, and by making the bottom of brass I cansolder directly thereto and avoid the expense of a special couplingconnection to do the soldering upon, as heretofore.

VVhat I claim is 1. In flush-tanks, a water-tank having alaterally-extending flange about its bottom all around, a casingtherefrom recessed about its bottom'to receive said flange, and aseparate bottom for said casing overlapping said flange, substantiallyas described. g

2. In flush-tanks, a water-tankhaving a grooved flange about its bottomoutside the Wall of the tank and an outlet down through said channel, incombination with an inclosremovable bottom overlapping said recess anding casing for said tank recessed to receive flange, substantially asdescribed. 10 said flange and provided with a hole in its WVitness myhand to the foregoing specifibottom coincident With the outlet from saidcation this 31st day of January, 1902.
